    • Towards shifted NMF for improved monaural separation 

      Jaiswal, R.; Fitzgerald, D.; Coyle, E.; Rickard, S. (Signals and Systems Conference (ISSC 2013), 24th IET Irish, 2013-06)
      The ability of Non-negative Matrix Factorisation (NMF) to decompose magnitude spectrogram into meaningful entities has found use in many audio applications. NMF can be used to factorise audio spectrogram of a music signal ...

    • Vehicle speed estimation using GPS/RISS (Reduced Inertial Sensor System) 

      O'Kane, T.; Ringwood, J.V. (Signals and Systems Conference (ISSC 2013), 24th IET Irish, 2013-06)
      Land vehicle speed is usually measured by wheel speed or GPS. While these methods are adequate for some purposes, there are some drawbacks. Wheel speed may differ greatly from vehicle speed due to tyre slip. In addition, ...

    • Wireless communication using ultrasound in air with parallel OOK channels 

      Wentao, Jiang.; Wright, W.M.D. (Signals and Systems Conference (ISSC 2013), 24th IET Irish, 2013-06)
      The use of airborne ultrasonic transducers for wireless communication was demonstrated. The work used capacitive ultrasonic transducers to transmit coded binary signals through parallel air channels. On-Off Keying modulation ...

    • Wireless sensed environment for body area networks 

      McDaid, C.; Timmons, N.; Morrison, J. (Signals and Systems Conference (ISSC 2013), 24th IET Irish, 2013-06)
      In low power wireless body area networks it is envisaged that there will be communication between on-body devices and wireless nodes placed in the environment (sensed environment) to provide a range of applications including ...
